PewDiePie and T-Series became first YouTube channels to cross 90 million subscribers.
The historic feat was first achieved by the Swedish gamer Felix Kjellberg's PewDiePie, followed by the Indian production firm T-Series.
The battle between the two channels for the top spot on YouTube and the ensuing campaigns to get more followers was a key factor in achieving this milestone.

Traces of Enormous Solar Storm

A team of researchers has found traces of enormous solar storm in Greenland that struck ancient Earth around 2,600 years ago.
According to the researchers, the finding has provided a stark warning that another event of this size could not be too far away.
The team of scientists, which examined the chemicals preserved in Greenland ice sheet, concluded that the storm was nearly 10 times stronger than anything detected in past 70 years of modern measurements.

Movement of Water Molecules on Moon

NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft has observed water molecules moving around the dayside of the moon, a finding that may prove beneficial as the agency plans to put astronauts back on the lunar surface.
Lyman Alpha Mapping Project (LAMP) -- the instrument aboard LRO -- measured sparse layer of molecules temporarily stuck to the Moon's surface.
The study is an important step in advancing the water story on the Moon and is a result of years of accumulated data from the LRO mission.

SpaceX Dragon Demo Capsule

America's new commercial astronaut capsule will complete its demonstration flight with a splashdown in the Atlantic Ocean.
The SpaceX Dragon vehicle will leave the International Space Station (ISS) where it's been docked this past week and drop through the atmosphere.
It has a heat-shield to protect it from the high temperatures of re-entry.
The mission, which has no humans aboard, only a dummy covered in sensors, has gone according to the script so far.
Assuming the Dragon performs equally well in the coming hours, it will set the stage for the US space agency (NASA) to approve the vehicle for crewed flights.
